Children's bike helmet RockBros TT-32005 Shark, size M (54–58 cm), detachable jaw, black

RockBros TT-32005 Shark is a children's bike helmet in size M (54–58 cm) with a detachable jaw guard and a black finish. Designed for junior riders, this helmet balances protection and adaptability: it provides head coverage typical for protective helmets while offering the option to remove the jaw piece for increased ventilation or comfort during different riding conditions. The adjustable fit accommodates growing children within the specified size range and the shell shape targets both safety and a low-profile look suitable for everyday cycling and recreational use.

Advantages

The helmet features a detachable jaw guard that can be removed or reattached without tools, allowing quick adaptation between full-face and open-face configurations. Its size M fit (54–58 cm) is adjustable to provide a secure fit for many junior riders. The black finish gives a neutral appearance that pairs with a variety of bikes and clothing. Construction follows standard protective helmet principles to provide impact protection for the head during typical cycling events.

Suitable for

• Everyday cycling and short commutes for children
• Recreational riding in parks and on bike paths
• Learning to ride and gradual progression to longer rides
• Situations where quick switching between jaw-protected and open-face configurations is useful

How to use

Place the helmet on the child's head so the front edge sits just above the eyebrows. Adjust the internal fit system and side straps to achieve a snug, stable fit without excessive pressure. Fasten the chin strap and ensure it allows one or two fingers' space beneath the buckle. If increased airflow or a more open feel is desired, detach the jaw guard following the manufacturer's instructions; reattach it when additional lower-face protection is needed. Inspect the helmet for damage before each use and replace it after any significant impact.

Usage recommendations

Use the helmet for supervised cycling activities appropriate for children. Regularly check strap adjustment as the child grows and after any rough handling. Do not use a helmet with visible cracks, dents, or compromised foam; replace it if it has sustained an impact or shows signs of structural damage.
